ABSTRACT
This paper presents some aspects concerning the influence of the environmental factors from 2008-2010 on the both sweet cherry tree growth and fructification. The agricultural years 2008 (a rainy one) and 2009 (a droughty one) can be described as years with special climatic characteristics which influenced negatively the biometrical growing and the tree production in this area. The meteorological factors (during 3 years) were analyzed, the fruit’s production (kg/tree) on varieties was calculated, measurements and biometrical determinations for tree and shoots (the trunk’s cross-sectional area and the length of the annual increases) were made and the correlation coefficient (r) between trunk’s cross-sectional area, length of the annual increases and fruit’s production was determined. In terms of 2008 which was an unusual year with an excess of 338,4 l/m2 rainfall compared to the multiannual average and of 2009 which was very droughty with a deficiency of 144,4 l/m2 compared to the multiannual average, ‘Cociu’ and ‘Ludovic’ were noted as the most resistant to drought.
